Algo Trader | São Paulo, Brazil

After losing my source code, I thought I would have to rebuild my EA from scratch. That would have taken months. I decided to try this decompiler service, even though I was unsure at first. The pricing was above average, but I could tell they knew what they were doing. They managed to recover my MQ4 from the EX4 file and delivered a structured code that I could understand and edit. That saved me an incredible amount of time. I also asked for some modifications, and they handled it without any issues. The final EA performed exactly as expected. This is not one of those fake services. These are real experts who get the job done.

I was stuck with an EX4 file and no way to edit it. I needed to make urgent changes to my EA, but without the source code, I was completely blocked. I found this service and decided to give it a try. Honestly, the price made me think twice, but I needed a solution. They didn’t disappoint. They decompiled my EA and provided a working MQ4 file. Not only that, they helped me tweak the strategy to better suit my trading style. Everything worked perfectly when I tested it. The process was smooth, and they communicated clearly throughout. No stress, no confusion. Yes, it’s not cheap, but if you’re serious about your trading tools, it’s a solid investment. They are real, reliable, and professional.”

I had almost given up on recovering my EA after losing the original MQ4 file. Every developer I contacted either said it wasn’t possible or tried to charge upfront without any clear explanation. This service was different from the start. They explained the entire decompilation process and what I should realistically expect. That gave me some confidence, even though the pricing was higher than I anticipated. When I finally decided to proceed, they handled everything professionally. They successfully decompiled my EX4 file and returned a usable MQ4 source code that I could actually work with. That alone was impressive. What really stood out was their ability to modify the EA afterward. I requested changes in entry logic and risk settings, and they implemented everything smoothly. The cost might feel high initially, but once you see the result, you realize it’s worth it. These guys are legit and deliver exactly what they promise.

As a developer myself, I know how complex EX4 decompilation can be. That’s why I was very selective when choosing a service. What impressed me here was their technical accuracy. They didn’t make unrealistic promises. Instead, they explained the limitations and possibilities clearly. The decompiled MQ4 file I received was well-organized and functional. It required minimal cleanup, which is rare in this type of work. They also assisted me in refining parts of the code and implementing additional features I needed. The pricing reflects the level of expertise involved. It’s not cheap, but it’s justified. I would definitely recommend them to anyone serious about recovering or modifying EA files.

I had an EA that was performing very well, but I lost access to the original source code. I needed to make updates, but I was stuck with just the EX4 file. After searching for a reliable solution, I came across this service. I was hesitant because of the cost, but I decided to proceed anyway. They delivered exactly what I needed. They decompiled the EX4 file and provided a usable MQ4 source code. On top of that, they helped me modify the EA to improve its performance. Everything worked perfectly after testing. The service is legit, and the team clearly knows what they’re doing. If you need real results, this is the place to go.

I’ve worked with several developers before, and most of them failed when it came to EX4 decompilation. This service proved to be different. They successfully recovered my source code and delivered a working MQ4 file. The structure was clear enough for further development, which is not something you usually get with decompiled files. I also requested additional modifications, and they executed them perfectly. The pricing is on the higher side, but you’re paying for real expertise and results. I can confirm this is a legit and professional service.
